R-Patz and K-Stew open up on Breaking Dawn's steamy scenes

The stars are getting set to start work on the final Twilight instalment - which starts filming this October - and already they’ve been able to sneak a peek at the script.

And now Kristen has been chatting about the movie's racier moments, promising bosses will stick to the script as the scenes heat up.

'It does actually literally get more physical [in Breaking Dawn],' she revealed to Access Hollywood of the couple’s sex scenes.
'It doesn't get more action-packed … [But] they definitely get more physical. Well, they get married. 'They're man and wife now. They have a kid and stuff too, so, I guess to get there that happens,' she adds.
'We totally have sex – finally!'

And R-Patz revealed there’s one scene in particular he’s looking forward to filming in the brand new flick.
'I'm looking forward to the pillow-biting scene,' he joked. ‘I thought that was so funny. Of all the random things too do, really? He bites the pillow.''I can't wait to get all my body makeup on,' he said, adding he's looking forward to being 'especially pasty looking.’
